Ingredients

How to Make It

  • 1

    Marinate 500g of mutton with 200g of whisked yogurt, ginger-garlic paste, and turmeric for at least 2 hours.

  • 2

    Heat oil in a heavy pot and fry thinly sliced onions until they turn a deep golden brown, almost caramelized.

  • 3

    Add the marinated mutton to the onions and sear on high heat for 5 minutes, stirring to seal in the juices.

  • 4

    Add the dry spices: 1 tsp chili powder, 1 tsp cumin powder, and 1 tsp coriander powder; stir well for 3 minutes.

  • 5

    Reduce the heat to low, cover the pot tightly, and let the mutton cook in its own juices for 30 minutes.

  • 6

    Check the tenderness; if the meat is still tough, add 1/2 cup of hot water to help the slow-cooking process.

  • 7

    Continue cooking until the oil separates from the masala and the meat falls off the bone.

  • 8

    Garnish with fresh cilantro and let it stand for 10 minutes before serving with luchi or steamed rice.

Frequently Asked Questions

Which cut of mutton is best for Kosha Mangsho?+

Use bone-in mutton shoulder or leg pieces cut into medium chunks, as the bone marrow adds essential richness to the thick gravy.

How do I ensure the mutton becomes tender without overcooking?+

Slow-cook the mutton on low heat for at least 60-90 minutes, allowing the collagen to break down gradually while the spices permeate the meat.

Can I substitute yogurt if I do not have any on hand?+

While yogurt is crucial for tenderizing and balancing the heat, you can substitute it with a mix of whisked sour cream and a teaspoon of lemon juice.

What is the common mistake to avoid when frying the onion-garlic paste?+

Do not rush the browning process; the onions must be caramelized to a deep golden brown, or the gravy will lack the signature dark color and depth of flavor.
